There is a wine retailer/restaurant in my neighborhood that sells wine in the restaurant at retail prices. One condition they have is that they do not change glasses. In other words, if I order a bottle of red wine, drink it, and then order a bottle of a different red wine, they require that I use the same glass. The owner says not changing glasses is one of the ways he keeps costs down so that he can sell wine for onsite consumption in his restaurant at retail prices. I guess I understand that--but this guy seems to be making A LOT of money, so I find the reasoning ridiculous. Does anyone know of any CREDIBLE articles I can show this guy that would put him in his place? Or am I the one being ridiculous?
